This Excel spreadsheet is provided by FANUC as an aid to determining the Wrist Load conditions of particular robots.

Every effort has been made to ensure that the spreadsheet data and formulas are correct, but FANUC does not guarantee that it is free of errors.

There may be some error margin between the load calculation result of this Excel file and the load calculation result of the robot controller.

The value of the gravitational acceleration used to calculate from V7.20 of the Excel file is changed from 9.81 to 9.8. Therefore, there is some error margin between the load calculation result of the Excel file on the previous version, 

the load calculation result of the robot controller, and the load calculation result from V7.20 of the Excel file.

It detects the limit level reliably and with millimetre accuracy directly at the mounting position. Numerous process fittings, approvals as well as housing and electronics versions.

The VEGASWING 61 is a universal level switch for use in all liquids. Independent of the mounting position, it detects reliably with millimetre accuracy the limit level. The instrument can be used as empty or full detector, as approved overfill protection, dry run protection or pump protection in vessels and pipelines. The VEGASWING 61 offers maximum reliability in a wide application range.

This manual was written for design engineers to enable them to choose appropriate fasteners for their designs. Subject matter includes fastener material selection, platings, lubricants, corrosion, locking methods, washers, inserts, thread types and classes, fatigue loading, and fastener torque. A section on design criteria covers the derivation of torque formulas, loads on a fastener group, combining simultaneous shear and tension loads, pullout load for tapped holes, grip length, head styles, and fastener strengths. The second half of this manual presents general guidelines and selection criteria for rivets and lockbolts.

Helical spring washers can be seen everywhere，but foreign production of machine tools, robots, manipulators, chemical pumps and other high-end equipment can hardly see helical spring washers, is it foreign engineers in order to cut save costs?

Valve stem seal generally used packing seal, packing by compaction to achieve sealing. Common fillers are graphite, PTFE V-rings, etc.

1. Add belleville spring at packing gland to realize continuous sealing

As shown in No. 7 of the following figure, 2 belleville spring are added above the packing gland.

Kamlok Series

Kamlok® Quick Disconnects are the industry standard in cam and groove couplers for safety and ease of use. All OPW Kamloks® feature the exclusive Twin-Kam™ arm design to help prevent accidental release, and Spring-Ring™ to ensure proper position of finger rings for ease of operation.

Loading Skid with APT RP 1004 Coupler.

The guide rail on the machine tool is divided into two kinds: linear rail and hard rail, the accuracy of the linear rail is higher than that of the hard guideway, but the hard rail is more durable and durable.

1. Linear guideway

It is our common linear guide rail, the linear guide rail itself is divided into two parts: the slide rail and the slider, the slider has an internal circulation of balls or rollers, and the length of the slide rail can be customized. It is a modular component, a standardized series of individual products produced by specialized manufacturers, which can be installed on the machine tool and disassembled and replaced after wear. The linear rail is rolling friction, which is fast, has low resistance, and is also convenient for lubrication.

The principle of the pilot operated check valve is similar to that of the pressure holding valve, the exhaust port also needs to be vented before it can be opened, and if the air is cut off, the exhaust port will automatically close to prevent the cylinder from falling.

Just studied Japanese and German robots in the workshop, and found that slightly larger robots, J2 will be equipped with a balance cylinder, Japanese FANUC robot uses spring type balancing, German KUKA uses hydraulic type (diaphragm accumulator) or counterweight block method, I personally think that hydraulic (diaphragm accumulator) way is the best, the output is basically constant, and it occupies little space.
